Re: (ET) 3 - 12v battery setup
I would go with something like a 105 amp hour deep cycle marine battery
(you would need to check the fit). I think it would be fine for light
duty. Walmart often carries these.
I don’t think the charger would be a big deal. The smaller battery set
would likely pull less amps. The time might not be very different but
you could check it with a voltmeter or specific gravity tester to confirm
state of charge and charging time.
